SPECIFICATION formingpart of Letters Patent No. 237,049, dated January25, 1881. Application filed April 12, 1880. (No model.)

To all whom it may concern:

Be it known that I, ARTEMAS PUSH, of Leon, in the county of Decatur andState of Iowa, have invented certain new and useful Improvements inSaw-Sets; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it pertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to an improvement in saw-sets; and it consists incertain novel devices comprised therein, as the trip'hammer, trigger,and adjustable gage, and in the means employed for operating the hammerautomatically, and also in the combination and arrangements of theparts, as hereinafter more fully set forth.

In the drawings, Figure 1 is a side elevation of my device. Fig. 2 is asimilar view of the reverse side thereof, and Fig. 3 is a view inperspective.

A indicates one of the handles of the device, which extends forward atthe point remote from the handle proper, to provide a suit ablereceptacle for the set-screw a, which lat ter is designed to regulatethe position or angle of inclination of the saw by supportingit at themoment when the punch D is caused to impinge conjointly upon the saw andanvil d.

B represents the under handle or plier, whose extension forms the jaw g.

The gage e is provided with the vertical flange 0, and it has asemicircular piece cut therefrom at the point where the punch D strikesthe anvil d. It is also provided with the metallic guide E, which isrigidly attached to the longitudinal plate of the gage c. In this plateis provided a longitudinal slot, through which the set-screwf, Fig. 2,projects, the latter being designed to hold the guide steadfast whenadjusted to the tooth ot' the saw.

The trigger F is pivoted by means of the screw it, projecting through anorifice provided in the lower part thereof, and caused to operate by thewire spring I), which is rigidly secured to the handle A at one endthereof and hooked to the trigger F at the other. lVhen the handles areopened the top of the trigger comes beneath the stud or pin 1), locatedin the hammer G, and as the handles are closed the trigger is pushedfrom under said pin by a corresponding pin, (1, in thejaw of the handle,as shown.

To the handle or plier B is rigidly attached, by the screw 0, thelongitudinal spring h, which projects into the shoulder h of the hammerG, as shown.

The hammer is pivoted in the frame 2',wbich latter is rigidly secured tothejaw g,- and when the trigger l is sprung by compression of thehandles A and B, at the moment when the punch l) impinges upon the toothof the saw, the hammer descends upon the head of the punch andeffectually completes the work.

The punch D is provided with the spiral spring 9, which adjusts it, andalso increases the resistance or requisite pressure upon thehandles, andhence the pressure upon the tooth; and it is provided with the pinm,which works in the vertical guide a in the jaw g. The guide preventsthe punch from turning and holds it in exact position in its descent andpressure upon the tooth, and the hammer strikes the tooth when thepressure is greatest, as aforesaid.

\Vhat I claim is- 1. The combination of the handles A and B, guide E,punch D, trigger F, and hammer G, operated by longitudinal spring h,substantially as shown and described.

2. The combination of the handles A and B, trigger l, punch I), havingspring g, hammer Ur, spring It, and jaw g, having guide a, substantiallyas shown, and for the purpose described.

In testimony that I claim the foregoing as my own I atlix my signaturein presence of two witnesses.
